Abstract (en)

In differential scanning calorimetry of a toner, regarding a binder resin in the toner, (i) the peak temperature T10 of a maximum endothermic peak (temperature raising rate 10.0°C/min; P10) is 50°C to 80°C and the half-width W10 is 2.0°C to 3.5°C and (ii) W1, W10, and W20 satisfy that W1/W10 is 0.20 to 1.00 and W20/W10 is 1.00 to 1.50, where the half-width of a maximum endothermic peak (temperature raising rate of 1.0°C/min; P1) is represented by W1 (°C) and the half-width of a maximum endothermic peak (temperature raising rate of 20.0°C/min; P20) is represented by W20 (°C).
